LUTHER A. MARSHALL, OF FLOYDADA, TEXAS.

JOY ROAD.

Application led June 5,

'70 all whom, it may concern.'

Be it known that I, LUTHER A. MARSHALL, a citizen of the United States, residing at Floydada, in the county of Floyd and State of Tcxas,have invented a new and useful .Toy Road, of which the following isa specification.

The device forming the subject matter of this application is a joy road, meaning thereby that the road is so constructed that persons will be willing to pay toll for travelling along it, because the road produces, upon the occupants of a vehicle, a peculiar impression not conveyed when the vehicle moves along an ordinary highway, the road which formsthe subject matter of this application consisting of a plurality of undulations. A further object of the invention is so to construct the road that it may be made cheaply.

It yis within the province ofthe disclosure to improve generally and to enhance the utility .of devices of that sort to which the invention appertains.

Although preferred forms have been shown, it will be understood that a highway engineer, working within the scope of what is claimed, may make such changes as his skill may dictate without departing from the spirit of the invention.

ln the drawings Figure 1 shows, diagrammatically in vertical longitudinal section, a straight road constructed in accordance with the invention; Figure 2 is a top plan of an annular road embodying the invention; Figure 3 is a section on the line 3-3 of Figure 2; Figure 4 is a section on the line 4 4 of Figure 2; Figure 5 is a section on the line 5 5 of Figure 2.

Referrin to Figure l, the road has a plurality 0% transverse undulations 1 adapted to be traversed by an automobile 2. The undulations 1 are excavated, as at 3, below the normal surface 4 of the soil, and are built up, as at 5, above the normal surface of the soil, the cut 6 between adjoining undulations being substantially equal to the fill 8 of one of the adjoining undulations, therebyl avoiding the makin Y of borrow pits, and avoiding the haulin o material a considerable distance in or er to make theill shown at 8.

When the automobile 2 traverses the road, the occupants of the automobile will be afforded a sensation which will be understood readily without further description.

1924. Serial No. 718,097.

lf desired, the road may be of the annular form shown in Figure 2 of the drawings, the surface of the soil being designated by the numeral 9, the crown of each undulation being designated by the numeral 10, and the numeral 11 designating the bottom of the depression between the crowns of adjoining undulations. As shown in Figure 3, the surface of the road slants upwardly and outwardly, at the depression of each undulation, from the inner edge 15 of the road to the outer edge 16 thereof. The height 12 of each undulation has a constant ratio to the distance 14 between the crowns of adjoining undulationsat all points between the inner edge 15 of the road and the outer edge 16 thereof: that is, if the distance along the line 4-4 of Figure 2 is forty feet, and if the depth o'f the depression is four feet, then, if the distance along the line 5 5 of Figure 2 is twenty feet, the height of the undulation is two feet. The result is that whether `the automobile be moving around in a circle which is close to the inner edge 15 of the road, or around a circle which is close to the outer edge 16 of the road, the amount of rise and fall has a constant relation to the distance traversed in moving circumferentially of the road between the crowns of adjoining undulations. In the form shown in Figure 2, the advantage incident to making the cut equal to the fill, as hereinbefore explained, is preserved.

If desired, the entire road may be built above the surface of the ground, and, of course, may be made of any suitable road building material.

I claimz- 1. A road lled by altering the natural surface of the earth, and so constructed that it may be traversed by automobiles, the road comprising a plurality of undulations disposed transversely of the line of automobile travel, the depth of the undulationsand the distance between the crowns of adjoining undulations being such, compared-With the length of an automobile, as to give a wavelike motion to the automobile.

2. A road of annular form, comprising radial undulations, the height of the undulations bearing a constant ratio to the distance between the crowns of adjoining undulations at all. points between the outer edge of the road and the inner edge thereof.

3. A road of annular` form, comprising radial undulations,v the height of the undulations bearing a constant ratio to the distance between the'crowns of adjoining undulations at all points between the outer edge of theroad and the inner edge thereof, the undulations being excavated below the normal surface of the soil and being filled above the normal surface of the soil, the

cut between adjoining undulations being substantially vequal to the fill of one of said undulations thereby avoiding the makingof borrow pits and the hauling of material.

In testimony that I claim the foregoing as my own, I have hereto aixed my signature. Y

LUTHER A. MARSHALL.,
